@Martine:
sure and in the end it looks ugly and totally unecessary (on top of being VERY forced). Since Oda is involved with the movies they wear all sort of dumb clothes to make money obviously.
cringe level over 9000

Anyway, traditional clothes >>> dumb and overfashioned clothes.
Some clothes are dumb others aren't, Oda likes to play a lot with designs specially in movies I think he feels like he can make them wear whatever because it doesn't have to follow any cannon logic.
Such as the "dream" clothes in the movie Z. Imagine in the middle of Zou or dressrosa they can't go around wearing shark hats and other silly wardrobes so I think Oda likes to have fun.
Other designs are obviously more commercially oriented but I didn't mind them changing into trendy wear as it could be chalked to them "dressing" like the inhabitants of the island they were visiting.
Of course, a new set of figures will come out for each of the appearances, but meh, doesn't mean we have to buy them .
